The military country of Baron is one of the strongest in the land, with a proud army and a majestic air force known as the Red Wings. However, the recent actions of the king make even the most loyal of his subordinates doubt his judgment. The captain of the Red Wings, Cecil, is ordered to attack the city of Mysidia and take the Water Crystal from innocent magicians who protect it. When Cecil questions the king's orders, he is immediately thrown out of the country and sent off to deliver a package to the village of Mist, accompanied by his best friend Kain, the captain of the dragoons. Little does he realize that the king's inexplicable behavior is but a part of a much larger picture, which he is yet to reveal.
The fourth entry in the Final Fantasy II series was released on PSP and features a Japanese-style RPG with top-down world map navigation, automatic leveling up, and random enemy encounters. The game is an RPG with RPG elements, set in a fantasy world.
The gameplay involves the ATB system, where combat is turn-based but enemies continue to act in real time while the player accesses the battle menu. Each character has a special bar that gradually refills itself, allowing them to act when the bar is full. The game does not allow players to customize their characters' abilities and classes, with each character belonging to a specific class that determines their special abilities or magic spells.
The PlayStation version of Final Fantasy II adds a new rendered intro and ending.
